Abstract
We demonstrate a novel optical pressure measurement platform for microfluidics. The pressure sensors operate as pneumatically-tunable microlenses whose focal lengths vary with pressure. We show that pneumatic lens arrays can be used to perform sensitive multiplexed pressure measurements in microfluidic channels.
